Gram-scale synthesis of single-crystalline graphene quantum dots derived from lignin biomass

Abstract

Renewable, cheap and green biomass resources could meet the urgent need for producing graphene quantum dots (GQD) in large scale if high quality can be obtained. Here we report the gram-scale synthesis of single-crystalline GQDs derived from lignin biomass via a two-step method. The synthetic processes involve the oxidized cleavage step followed by the aromatic refusion step of alkali lignin molecules. Notably, this approach successively converts the commonly considered biomass waste into high-valued nanoscale product. As-prepared single-crystalline GQDs, present hexagonal honeycomb graphene network, are 1-3 atomic layers thick. Due to the bright fluorescence, up-conversion property, long-term photostability, water solubility and biocompatibility, these high quality GQDs are potential to be excellent nanoprobes for multicolour bioimaging. The utilization of renewable biomass resources paves the way for green, low-cost and large-scale production of high quality GQDs and allows for the development of sustainable applications.
